Abstract
A method and apparatus for spraying particulate powder material into a continuous roving or tow formed of individual strands comprises a hollow spraying chamber having inlet and outlet guides for receiving the tow moving axially therethrough. A stream of air-entrained particulate powder material is injected into the hollow spraying chamber, at an angle relative to the direction of movement of the tow, with a velocity such that the individual strands of the tow are separated from one another and the particulate powder material is lodged between the exterior surfaces of adjacent strands throughout substantially the entire thickness of the tow.
